Abstract

The invention discloses a high-reliability mining elevator hydraulic control system. The system comprises a first motor, a variable pump, a high-pressure pipeline, a low-pressure pipeline, a high-pressure safety valve, a low-pressure safety valve, an oil tank, a first pump-motor, a second pump-motor, a safety check valve set, an energy accumulator set, a pressure sensor, a rotating speed sensor, a second motor, a hydraulic pump, an overflow valve, a one-way valve, a pressure reducing valve, an electromagnetic reversing valve, a brake cylinder, an oil replenishing tank and a control oil source; and further, a variable mechanism of the variable pump comprises a variable cylinder and a servo valve. The system realizes the energy recovery and the stable-speed control of a mining elevator, and effectively improves the energy utilization efficiency and the working performance of the mining elevator.

Description

technical field [0001] The invention relates to the field of mining machinery, in particular to a high-performance mining hoist hydraulic control system. Background technique [0002] Mining hoist is one of the key equipment in mining machinery, and it is an important transportation hub connecting the mine and the mine. Its working performance will directly affect the working efficiency of the entire production line, and even relate to the lives of thousands of mine workers. [0003] At present, the mining hoist is usually driven by a hydraulic system, and the braking resistance is provided through the brake disc. However, the existing mine hoists generally have technical defects such as unrecoverable energy, serious consumption, and unstable ascent speed. [0004] In order to overcome the technical defects of existing mine hoists, it is urgent to provide a high-performance mine hoist hydraulic control system. Contents of the invention [0005] In view of the above-ment...
